.l'atented Aug.. 18, 1914.

.Application filed April 1, 1907. Serial No. 365,8()1.

My invention relates to machines knownto the trade as insole nishinmachines,

wherein the reinforcing materia which has been applied to the insole andbeaded over or cemented to one or both sides of the rib or lip on saidinsole, is forced or firmly pressed against it.

My invention aims, generally, toimprove machines of this type byproviding simple and efficient means for properly defining lthe anglesor channels at the base of the lip of a reinforced insole by pressingthe reinforcing materialv against said base, to

. cause said material firmly to adhere thereto and also to the outerAmargin or feather of.

the insole. The above, however, with other A features and objects of myinvention, will be best understood and appreciated from the followingdescription and accompany ing drawings of a machine embodying one :formof my invention; and selected for purposes of illustration, its scopebeing more particularly pointed iout in the appended claims.

ln the' drawings; Figure 1 is an elevation of the left side of amachine, with arts broken out, embodying one form o tration; Fig. 2, afront elevationthereof; and Fig. 3, a vertical, sectional detail toillustratek the action of the rollers upon the reinforcing materialsat'the base of the lip.

Referring to the drawings and to the particular embodiment of myinvention herein selected for purposes of illustration (see Fig. 1), themachine is provided with -suii;-

able means, here shown as a rotary Workmy invention and selected forpurposes of illusthe body of the insole adjacent said lip. Jl`h e rotarytools, preferably provided 'for this purpose, comprise Wheels orrollers, 5 (Fig. 3), having narrow and curvilinear rims shaped to fitinto the channels or angies at the base of the lip and to force thereinforcing fabric into said channels, the lip with its cover ofreinforcing material extending above said wheels, so.' that it may yieldor curve over slightly under the ac-v tion thereof (see dotted lines,ll1`ig. 3), to permit forcing or tucking the fabric firmly against thebase of the lip and to cause it to adhere thereto.

The rotary work table l and the rollers 4 70 and 5 are forced intooperative relation with one 4another by the action of suitable springs,hereinafter described, to effect continuous pressure upon thereinforcing fabric at the oase of the lip and the portions ofthe insoleadacent thereto, so that when the insole has )een run through the.machine, the channels at the base of` the lip are properly defined orformedvand the in sole prepared to have the upper efficiently 'n.stitched thereto. For mounting or supporting and operating the table'land said rollers 4 and 5 and their connections, I provide a suitablesupporting frame comprising, in

the present instance, a base 6 (Fig. l), 85

adapted to be secured to a bench or, prefer ably and as here shown, tothe 'head of a column 7. Rising from this base are uprights 8, providedat their heads with suit-- able bearings 9, for a horizontal drive shaftl 10, having loose and fast pulleys 11 and 12, respectively, at its leftend (Fig. 2), adapted to be rotated from `any convenient source ofpower. Intermediate its bearings 9,' said drive shaft 10 is providedwith a large 95 Worm 13 (Fi 1), in mesh With aninclined I 'Worm-Wheel1gb, fast'on an inclined shaft 15. This shaft isrotatably mounted inupper and lower inclined bearings 16 and 17 (Fig.A

1), respectively, the latter being preferably 100 integral with the base6. As here shown (Fig, 2), the upper bearing 16 is centrally formed upona yoked bracket 18, securedin any suitable manner to the heads of saiduprights 8, as by the rearvv'ardly extending 105 horizontal lugs'19 andsecuring bolts 20.

At its front, the base 6 is also provided .with

a vertical, tubular bearing 21 for the supj porting shaft 22 ofthetrotary vyork table 1T said bearing being bolted to said base at 23.11n

. upper and lower bearings 25 and 21 respecwith said bevel gear tainingsaid shaft,

.fabric is .bea-ded.- It will those skilled in the F. bearing 21 isprovided with haie At its head, this bearing has upper arm of which isformed to provide an upper shaft bearing `25, which, in the presentinstance, is bolted at 27 to a forwardly projecting arm 26 of thebracket 18. By this construction the separable parts of the frame aresecured together to ,form a rigid spportforthe operative parts of themachine. l

For rotating the work table 1', the in-1 elined shaft 15 isprovided,between the bearing 16 and the worm-wheel 14, with a i bevel gear Wheel28, in mesh with a bevel gear29, splined on' the vertical shaft 22 whichcarries` the 'work tablerl. This shaft is slidably aiidvrevolublymounted in said tively, and, through the splined connection of saidtable. The gear wheel 29 is rotatably mounted between said bearin s 25,2l, 'and the arms of the yoke 24, the horizontal upper supportin face ofthe lower bearing 21 being prefera ly provided with a suitableanti-friction bearing,

as the ball bearing 30, to facilitate rotation thereon.

recess 31', of suliicient diameter to receiveand lift the tableuiiderthe pressure of said ieldingly supporting it in op-l erative relationwith the rotary finishing wheels 4 and 5. This. spring, 32in the presisl interposed between an adjustable` nut or plug 33 (Fig. 1), threadedinto lthe bottom opening in the tubular bea'ring 21, and a colla-r 34adjustably secured 'on said shaft 22. The nut 33 is apertured to 'permitthe shaft 22 to slide therein and by adjustably securing said nut in thebearing 21, suitable and convenient'means are provided for varying thetension of the elevatingl spring 31. and, hence, the lifting forceapplied to said'table 1. ,y

To provide means for conveniently depressing or lowering the worktablel, so that the feather or marginal portion of the inse-le may beslid under the wheel 5, the lower end of the shaft 22 is connected inany suitable manner, here shown as by the swivel hook 35, and connection36, with a suitable controlling lever, preferably a treadle 37,

pivoted at the base of the column. The

tread of this treadle extends forward at the side of the machine, withinconvenient reach of the operators foot, so that it may be readilydepressed to pull down the table when an insole isto be inserted orremoved.

The rotary work member or -tool 5 is sehead of the inclined shaft 15shown at 38. This wheel roosition and coperates with the table 1 to c amthe outer marginal portion or feather ci) theinsole between 'itscorrugated'face and the horizontal face of the spring supported worktable, beyel gears of the rotary shafts 15 and `22 fates in fixedthrough the action of the Worin 13 and wo'rm wheel 14, causesthesegears,` and hence the work table 1 and said roller 5, to-i-otate inopposite directions, thereby causing the adjacent insole'engagingportionsthereof'to.

To provide suitable means formountingr and operating this Wheel 4to secure these results, the arms 4l(Fig. 1) of the' ycked bracket 18 are extended vertically and, at theirupper ends, are provlded with' suitable bearings for a rotary shaft.This shaft furnis the fulcrum for a horizontal .angular lever 43, thefront arm of which is provided with an inclined socket-bearing lug 44,yWithin which is rotatively and slidably mounted the shaft .45 of saidWheel 4'.. This shaft is no rn'iallymain-l tained depressed, to causethe wheel topress the work, bya coil spring `46 surrounding said shaft,the cylindrical recess 47 in theloujer end. of the bel'lg lug 44 beingen? iarged to receive the shaft tand its spring. 7his spring isinterposed between 21D adjustable collarfl, threaded on the shaft ofsaid tool and slidable in said recess 47, and a shoulder 49 of thelatter, so that the shaft and its wheel are normally forced down to-Ward the table, to cause its rim tofenter and -run in the inner channel,at the base of the lip, and under a pressure that, may be regulated byvaryingl the tension or' said spring, through adjusting the collar L48.To co; operate with this spring 45 in' 'producing the desired verticalpressure upon'v the insole, the outer or front arm of the carrier lever43 is normally'depressedand theroller 4 swung I inward by the action ofthe ,Sellin-coil spring 40,v to which referencehas been made, and whichVconnects the shaft bearing 44 with a .tv ork., That suita Cylindrical,vertical yoke erm .41 ef he ,breket le This spring, however, is alapted to yield to permit swinging the Wheely e .foi-'eier when the,table iS depressed for eenrenleuee 1n iueertmg and peeitloning theinsole or be means mey beprevded to feCt this movement, and prteehllysimultaneously ,with `the depression of the work Support, .the reer ermof thelever 43 is ,provided with afiexible connection for connecting itwith .the ,treadle 37, .for example ,thejcord 50, which runs over guidePulleys 5l, 52, and is Connected yas at 53 wth' said treadle B7. By thisarrangement, the depression of the trcadle not only lowers h rWorktable, but swings the Wheel 4 away from .its cooperating Wheel 5, sothat the AnSoleZ and its lipl 3 niay be placed in proper positierelative to thelwheel When an insole' as been placed in 'such position,release of the .treadle causes the table to rise through the action ofits sprinff, to clamp the insole between the table andrim of,the wheel5, the rim .of lthe Wheel 4 ,simultaneously ver i,gasgi1 1g the frontofthe lip te 'press 1t and clamp itagainst said wheel 5.

For rotating theworklngtool or Wheel 4, .its Shaft .45 is provided W1tha ,Worin-Wheel 54, lin mesh with a worm 55 y fast on the upperhorizontal Shaft 42, .said shaft being driven by the rotation of a largegear 56, fast on tsr-ight end, in mesh with a similar large gear 57011the`corresponding end of the drive shaft 10, the rotation of which'rotates the upper gear wheel i6 and thereby seid worm 1 55, Worin-Wheel54 and Working" Is ,uppo'rt and said wheel 4 to their normalinsole andlip. clam ing or pressing positions With the lip con ned and pressedbetween the Wheels 4 and 5. The machine is then started, in the usualmanner, to effect rota-1 tion of the Work support l and Wheels 4 and 5,as described. By the simultaneous action of these members 4 and 5, theinsole 'gripped between them is continuously fed eoA from right to left(Fig. 2) and the fabric pressed iirinly-to place to properly dei'ne andform the channelsat the opposite sides or base of the lip, where ,thestitching strain is apt to comewhen the uppers are secured thereto.

The action of the machineis rapid and it does its work in a thoroughly'efficient mannen'so that the fabric is set and its adhesion -to theleather secured at the points `fabric is drawn upon to furnish materialin forming said channels and Where 1t had been improperly applied,'itbeingpof more importancev to properly define the channels; `than thatsaid lip should stand up straight, style to they since the channels giveshape or shoe.

My invention, obviously, is not limited to` the particular embodimentherein selected for urposes of illustration only, nor to the specificdetails of construction and arrangement, but iscapable of modificationWithin Wide limits, lWithout departing from the spirit and scopethereof.
